UNITED STATES PATENT OFFICE TOBACCO PIPE David Russell Herriott, Glendale, Calif.

Application March 9, 1948, Serial No. 13,870

3 Claims.

The invention relates to a tobacco pipe and more particularly to a pipe having a cleaning device attached to the bit so that the bit can be operated to clean the device. The cleaning device is also of such a nature as to condense the tar from the smoke while the pipe is in use and while the bit and the cleaning device are stationary.

An object of the invention is to provide an improved device for cleaning the fluid in the stem and to permit its removal by blowing through the bit.

Another object of the invention is to provide a tobacco pipe having a blow-out opening controlled by a valve head on a movable bit,v with means yieldingly retaining said valve head in position to close the blow-out opening, for smoking purposes.

Another object of the invention is to provide a bit which may be operated to clean or remove the heel at the juncture of the bowl with its stem or to ram and loosen the tobacco at that location so that the pipe will draw better.

Another object of the invention is to provide a mechanical filter for the smoke, the filter forming a permanent part of the pipe and not requiring replacement. f

For further details of the invention reference may be made to the drawings wherein- Fig. l is an enlarged vertical sectional view of a l tobacco pipe according to the present invention, the bit and its attached cleaning device being shown in one position for smoking.

Fig. 2 is a sectional view like Fig. 1 with the operating parts in cleaning position.

Fig. 3 is a sectional View on line 3--3 of Fig. 1 looking in the direction of the arrows.

Fig. 4 is an enlarged sectional view on line 4--4 of Fig. l looking in the direction of the arrows.

Fig. 5 is a longitudinal sectional view of a modified construction.

Referring in detail to the drawings, the tobacco pipe I comprises a bowl 2 preferably of briar and having an integral short shank 3 having a threaded bore 4 which opens into the interior 5 of the bowl at its lower end. Threaded into the bore 4 is a metal coupling 6 having a central external diameter preferably the same as that of the shank 3 and having an aperture 'I for a spanner wrench so that it can be screwed in or out. The coupling 6 has a threaded extension 8 which fits into the bore 4 so that its end 9 is substantially iiush with the wall I0 of the bowl, While the bore II which extends through the coupling 6, at its lower portion I2 is substantially iiush with the bottom wall I3 of the bowl. The other end of coupling 6 has an extension I4 having threaded engagement I5 with a metal hollow stem I6. The coupling 6 has a shoulder I'I which abuts the end I8 of the shank 3 and also a shoulder I3 which abuts the end 20 of the stem I6. The stem I6 extends beyond the coupling I4, to provide a chamber 2|. The end 22 of the stem extension I6 is inturned and provided with a bore 23 to slidably'receive the rear end 24 of a cleaning device 25 of metal. All metal referred to above is preferably aluminum. The end 24 has a threaded nipple 26 to receive the threaded bore 2l in the bit or mouthpiece 28. The cleaning device 25 is therefore mounted on, carried by, and operated by the bit 28.

To prevent the bit 26 and cleaning device 25 from rotating, the end 24 has an enlarged circular head 29 which slidingly ts in the bore of the chamber 2 I. The movement of the bit 2B and cleaning device 25 rearwardly is limited by the shoulder 36 on the head 29 striking the shoulder 3I on the inturned end 22. The head 29 is provided with a longitudinal slot 32 and the stem extension I 6 is provided with a key 33' which rides in slot 32. As shown in Fig. 4, key 33 may comprise a sleeve 34 in threaded engagement 35 with the bore 36 through the wall of the stem I6. Sleeve 34 has an extended end 3l which rides in the slot 32. In the sleeve 34 is a spring 38 press-y ing on a ball 39 which rides on the bottom of the groove 32. Groove 32 has a recess 48 for the ball at the front of head 29, to frictionally hold the bit 28 and cleaning device 25 in the smoking position shown in Fig. 1.

The cleaning device 25 also comprises an integral elongated rod 46 which is smaller in diameter than the bore II of the coupling 6, to provide a smoke passage through bore II. The front end 49 of rod 40 terminates in line with the bowl Wall I0 when the device is in smoking position.

In the chamber 2I, the cleaning device 25 has a disk valve head 4I which slidingly fits in the cylindrical bore of chamber 2l. Valve 4I has in its periphery a plurality of spaced ports like 42 and 43 which extend lengthwise of the axis of the stem extension I6. In the smoking position, the ports 42, 43 are open so as to pass the smoke from the bowl to the bit, and in this position an imperforate portion 44 of the valve 4I closes a drain outlet 45 at the lower portion of the stem extension I6 in front of the bit 28.

The cleaning device 25 also has integral spaced baffles 46 and 41 between the valve 4I and the head 29, these baiiies being smaller in diameter than the bore of chamber 2 I.

The whole cleaning device 25, including rod 4U, valve head 4I, baffles 46, 41, head 29 and end 24 can be cast in one piece of aluminum, or machined from an aluminum rod. The smoke is cooled by contact with these parts and by contact with the inside of metal coupling 6 and stem extension I6.

The operation of the pipe in Figs. 1 to 4- is as follows:

When the parts are in smoking position as.v shown in Fig. 1, tar condenses from the smoke. on the exterior of rod 40 and on the adjacentYV Wall of the bore I I. The smoke proceeds'through' the ports 42, 43 and further condensation takes place on the baiiles 46, 41. Some' liquid accumulates in the lower portion of chambery ZIE which serves as a well and the head 29 is provided with a smoke passage 50 whichopens. atits lower; end above the well, this passage being inclined upwardly in a rearward. direction, and extending through the bit as shown at 53-so that liquidin the bit or in the rear end 24: of. the cleaning device will drain out of passage 50. into chamber 2I.

The stem extension.I I 6 isprovided withanaperture Iy for a Spanner wrench so that thestem extension can be removed fromy the coupling 6, this also permitting removal of the bit 28'andthe cleaning device 25 carried thereby so that these parts can be inspected or cleaned, but this should be necessary very seldom. During the usual-and normal operation of the pipe it is not necessary to take it apart as the smoke is cleaned andliquid is accumulated in the bottom of chamber 2I Without any special operation and in the normal course of smoking.

If an acoumulationof burnttobacco remains at the bottom of the bowl adjacent theend. 9 of the coupling, this canbe'loosened bypushing. on bit 23 which projects therod 40'forwardly so that its front end projectsl into the bowla's shownY in Fig. 3; When it isdesired.- toi-remove the liquid accumulated at the bottom of chamberr 2|-, the bit 28 is pushedforwardly to the'positioni'shown in Fig. 2, whereby the valvehead.-4.l strikes. the end 52 of. the coupling 6-which acts as astop to limit such forward movement, the' end 52 also acting as a valve seat to close the ports 42, 43'. When the Valve head-4I.- isn. that position, the exhaust outlet 65 isopenv as shown in;Fig. 2 and hence by blowing into the bit 28, whateverv liquid has accumulated in the bottomof chamber 2-I is blown out through outlet 45.

rEhe rod 49 alsoactsfasa ram to loosen. up tobacco at the lowerv portion-of thefbowl at the entrance to the coupling aas boththe-rod I0-'and the valve head di are integralV and asboth.A are mounted on and carriedby the bit 28, operation of the bit 28 by-pushing itin or out operates-both the rod 46 vandthe valve headdfl yat the same time.

As shown in Fig. 5, the bit |28 and its cleaning evice IRS may be resiliently heldin smoking position shown, by means of ahelical compression spring 60 the rear end ofv which bears against the valve head 64, itsforward end bearing against a shoulder 6I at the forward end of. bore.- 6'2.in the coupling 566. The spring,lfis-mounted-inthe bore 62` and retracts into it when. the bit.- |28. is pushed in. The bit |28 and its'cleaning device |25, similar to cleaningdevice 2.5above described,

.are guided for reciprocating non-rotary movement by a key I33 in the form of a screw through the wall of the stem extension I I 6, the inner end of screw |33 riding in a slot |32 in the head |29. The construction and operation of the pipe of Fig. k5 is otherwise the same as described in connection with Figs. 1 to 4.

It will be apparent that various modications may be made in the invention without departing from the spirit ofthe following claims.
